C tools or machinery, and the device is constructed in a simple mannertoinsure low cost of productlon, and may be operated with facility andconvenience in lubricating otherwise inaccessible parts.

The invention consistsin certain novel combinations and arrangementsofparts involving the feed and discharge parts of the oil can as willhereinafter be more fully set forth and claimed.

In the accompanying drawings I have illus trated one complete exampleand a modification thereof of the physical embodiment of my inventionwherein the parts are combined and arranged according to the best modesI have thus far devised for the practical application of the principlesof my invention. It will be understood that changes and alterations maybe made in the exemplified structures, within the scope of my claimswithout departing from the principles of my invention.

Figure 1 is a sectional view of an oil can of my invention of the pistoltype having a trigger operating means. Figure 2 is a sectional view of amodified type of can, but using the same feed and discharge means, andFigure 3 is an'enlarged detail perspective view partly in sectionshowing the cylinder construction. 1

In Figure 1 where the pistol type of trigger actuated device isillustrated, the can 1.

is of usual cylindrical construction and provided with a filling barrel2 that is normally closed by the screw cap 3. The barrel is utilized asa handle or hand-grip when the oil can is being manipulated forlubricating purposes, and the can and barrel may be filled or partiallfilled with oil that is to be pump ed or forced from the can.

Within the can an axially alined cylinder 4 is supported beneath astationary partition 5 which extends transversely of the interior of thecan and is fashioned with openings 6 for freedom of movement of oil atthe opposite sides of the partition. The partition has an annular flange7 in which theend of the cylinder fits, and at the opposite end of thecylinder a supporting yoke 8 is fixed to a head 9. on the cylinder. Thediverging arms of the yoke are supported at the end of the can and a tiebolt 10 which has a countersunk head in the screw cap 11 of the can, isthreaded into the head 9 so that the cylinder may be rigidly supportedwithin the can as shown in Fig 111871'.

At one side of the cylinder near its end an intake tube 12 is connected,said tube projecting into the barrel 2, and at itsfree end this tube hasa valve bushing 13 threaded thereon in which a ball valve 14 is enclosedand held to its seat by a spring 15. The ball valve nor-' mally closesthe valve bushing against entrance of oil to the feed tube or intaketube,

and the ball valve is opened against tension of the spring by suction orair pressure when the operating parts of the oil can are manipulated..As the ball valve is opened oil flows from the barrel into the tube andthence into the cylinder 4 after which the oil is-pumped fromthegcylinder by means of the piston 16 into the spout 17 of the can. 5 1

The piston isof course located within the cylinder and the spout,whichextends longitudinally ofthe center of the can, is passed throughan opening in the partition, and secured, as by screw threads, to thepiston. The piston is fashioned with a valve bushing 18 that forms anextension of the spoutand also forms the cage for a ball valve 19, whichthrough a springQO, normally closes the open end of the bushing, thelatter being formed as a valve seat adjacent the inlet end of the feed.tube =12. When the device is manipu lated, a charge of oil is fed fromthe tube 12 into the cylinder and past the ball valve as the latter is'removed'from its seat, and of The spout and its plston are adapted tobe reciprocated, and they are moved in one direction against the tensionof a spring 21 that is coiled about the spout and interposed between afixed collar 22 and the partition 5,

. and the spring moves the spout and piston in 1 of the piston in thecylinder discharges the oil and the forward movement of the pistoncauses suction in the cylinder and tube so that the ball valve 14 isopened to admit a successive charge of oil :to the cylinder.

At its end exterior of thecan the spout is pnovicled With a reducedextension 2% that may terminate ina curved nozzle 25 by means of whichotherwise inaccessible parts may be reached, or a nozzle 26, dottedlines Figure 1, may be used where oil plugs with ball valves are to belubricated.

The piston and spout are manually retracted through the manipulation ofa trigger 27 that is slidable in a bearing or guide 28 on the exteriorof the can, and the trigger is pivoted -.to a lever '29 that extendstransversely oat the spout and is pivoted thereon at 30. A link '31forms the pivotal support for the lever and said link is pivoted on thecan as indicated at 31c.

In Figure '2 the can 32 is provided with a cylinder 33 and the latter issupported from the partition 6 by a yoke 34, in addition to the tie bolt100;. A'looped handle 35 is provided for the can and the spring pressedspout and piston are retracted manually by manipulation of the thumblever 36 pivoted to the spout and also to the link 37 that is in turnpivotally supported at 38 on the can.

Having thus fully described my invention, What I claim as new and desireto secure by Letters Patent is a l. The combination with an oil canhaving a laterally extending filling barrel adapted to form handle, acylinder within the can, a feed tube in the barrel connected to thecylinder and a spring pressed intake valve in the tube, of a piston inthe cylinder having an intake valve, a spring pressed spout connected tothe piston in the cylinder, and a trigger mechanism for retracting thespout and piston to discharge the cylinder.
